 connector device

description

The invention relates to an elongate contact element for an electrical connector device.

The invention is based on a prior art, according to which electrical connector devices

 basically be designed as a socket or plug and usually a contact insert block

 in which inserted elongated generic contact elements in the case of a plug as an electrical connector device as elongated contact pins and in the case of a trained as a socket electrical

 Connector device are designed as elongated contact sockets. Such electrical

 Connector devices are in particular in the standards DIN VDE 0623, IEC 60309-1, -2, IEC 62196-1, -2 and EN

 60309-1, -2 described.

The contact elements used accordingly serve for the respective mechanical and electrical coupling with a complementary counter-contact element. One

 Serve mating contact element, hereinafter and in the claims also referred to as receiving section.

CONFIRMATION COPY Furthermore, such a contact element usually has an adjacent to the receiving portion or

spaced section leading to the mechanical and

electrical coupling or for receiving an electrical connection conductor is used.

The generic elongated contact elements thus consist essentially of electrically conductive material, conventionally of a metal.

EP 1 783 868 relates to such, as elongated

Contact pin trained contact element, which is formed from a flat solid material by punching and bending and along the receiving portion in the

Has substantially hollow cylindrical cross-section. Although the contact pin described therein satisfies the requirements of DIN VDE 0623, EN 60309-2 according to the description there and saves against hollow-cylindrical contact pins produced from solid material by means of cutting or abrasive removal of material, as well as against solid material contact pins, i. without hollow cylindrical cross-section, material included. However, according to EP 1 783 868, due to the punched out

Flat sheet bent contact pin edges

It has been shown that especially in such

 Edge spaces penetrating and possibly. remaining impurities and / or unwanted moisture

 Oxidations and / or corrosion can entail, which in turn can lead to increased contact resistance during power transmission as a result.

An object of the invention is to provide the aforementioned

 Counteract disadvantages effectively.

Contact element according to the invention for an electrical connector device (such as in Fig. 7A, 7B

shown).

The contact element has an elongated

 Receiving portion 101 and a first end portion 102, wherein the receiving portion 101 from the first

End portion 101 of substantially hollow cylindrical for mechanical and electrical coupling or receiving a complementary to the contact element formed, but not shown mating contact element to be paired with the electrical connector device Connector device extends. The elongated, hollow-cylindrical receiving portion 101 is in this case formed free of material transitions and formed of an electrically conductive material, as well as the first

 End portion 102 of this electrically conductive

Material is shaped. The first end portion 102 opposite end 103 on the receiving portion 100 is closed.

The hollow cylindrical receiving portion 101 is characterized by freedom from seams and freedom from material transitions, and thus is circumferential, i. on the cylinder-like surface completely, in particular hermetically,

closed.

As can be seen from FIGS. 1 a and 1 b, the elongated, hollow-cylinder-like receiving portion 101, including the regions 102 and 103, is formed from a flat material. In the illustrated embodiment, a circular sheet 100 has been used for this purpose, although other geometries and materials can be used, from which the elongated, hollow-cylindrical receiving portion 101, including the areas 102 and 103 by means

With application of the aforementioned preferred thermoforming or

Extrusion molding method, the first end portion 102 is formed with a kind of a circumferential collar 104. Becomes during deep drawing or extrusion of the "stamp" to the hollow cylindrical inner shape of the

 Inserted receiving portion 101 coming from the side of the then first end portion 102 forth, a less complex deep drawing or extrusion tool is sufficient to provide such or similar first
